Goals: While en route to its second comet encounter, the Deep Impact-EPOXI spacecraft's instruments were used to provide another lunar science perspective.

Accomplishments: Lunar data gathered by Deep Impact during its extended EPOXI confirmed Chandrayaan-1's discovery of water molecules on the Moon. Deep Impact observations revealed that the entire lunar surface is hydrated during at least some portions of the lunar day Data from NASA's Cassini mission also helped confirm the important discovery.
